Specification of Letters Patent.

Patented J une 9, 1914.

Application led August 25, 1913.` Serial No. 786,479. Renewed April 18, 1914. Serial No. 832,985.

To all 'whom t may concern.'

Be it known that I, HERMAN A. WEIDEN- BAoH, a citizen of the United States of America, and a resident of the city of Buffalo, county of Erie, Vand State of New York, have invented certain new and useful Improvements in Multiplying Centrifugal Governors, of which the following is a full, clear, and eXact description.

One of the objects of my invention has been to provide a governor in which the amount of movement of the rotating parts shall be multiplied in its effect on the reciprocating parts and also to provide means whereby the proportional movement of the rotating and reciprocating `parts may be changed at will.

Other objects have been to provide a governor, the working` parts of which shall be inclosed within a casing, thus making a very compact device and also protecting against injury.

Furthermore, my governor may be easily and quickly adjusted to govern any desired speed and it is very sensitive to the slightest change of the speed of rotation thereof.

Moreover, my device will be cheap to manufacture, constructed of few parts and thus will not easily get out of order.

Reference is to be had to the accompanying drawings forming part of this specification, in which likecharaeters of reference indicate like parts throughout the Several views of which:

Figure 1 is a vertical sectional elevation of my improved device and is taken on the center line of the same. Fig. 2 is a transverse sectional view of the same and is taken on line A--B of Fig. 1. Fig. 3 is a vertical sectional elevation of a modified form of my device. sectional view of the form shown in Fig. 3 and is taken on line C-D of that figure.

Referring now to Figs. 1 and 2 of the drawings, 5 represents the center hollow shaft of my governor which carries the parts of the governor and by which it is rotated. This shaft is provided near its upper end with two diametrically opposite lugs 6. In each of these lugs `is screwthreaded a stud 7. 8 are the casing parts of my governor which are pivotally mounted near their centers upon the studs 7. These casing parts are cylindrical about the axis of the governor and are cut away at the joint above the pivotal point, as shown in Fig. 4 is a fragmentary transverse Fig. l, so that they may have a slightrotation upon the studs 7. The lower end of each casing part is preferably formed with a recess or chamber 9 and in this recess is placed metal having a greater specific gravity than that from which the casing parts are made, thus providing the weights 46 for the governor. 10 are ears which are made integral with the upper end of the shaft 5 and these ears are disposed at right angles to the pivotal studs 7. Extending centrally through the ears 10 and shaft 5 is a slot 1l in which the link motion of the governor is adapted to work. Slidably disposed within the hollow shaft 5 is the governor spindle 12 and this spindle is also provided near its upxper end with a slot 13. 14 are levers w 1ch are dlsposed withinthe slots 11 and pivotally mounted upon pins 15 carried at the outer ends of the ears 10. These levers are bifureated at their inner ends and are provided with a plurality of apertures 1G. 17 are links which have their lower ends disposed within the slot 13 formed in the spindle 12, and pivotally connected to said spindle by the pin 18. The upper end of each of the links 17 is disposed within theslot formed by the bifurcated inner end of each of the levers 14 and s pivotally united thereto at any desired position by the pins 19. The casing parts 8 are provided with hardened steel bushings 2O which are preferably screw-threaded in the casing parts. These bushings are disposed diametrically opposite each other and preferably in the same plane as the studs 7. rlhe levers 14 are provided with outwardly extending arms 21 which are circular in shape and are disposed within the bushings 2O carried bv the casing parts. Disposed in the upper portion of the easing parts S and arranged diametrically opposite each other are adjusting studs 22. Each of these Studs comprises a smooth portion 23, a screw-'threaded portion 24and an integral collar 25 which separates the two portions 23 and 24. The portion 23 is provided with a slot in its outer end and is rotatably disposed in a suitable aperture in each of the easing parts. The screw-threaded portion 24 of each of the studs has arranged thereon a screw-threaded flange 26. Each of the flanges 2G has a pin 27 passing through its rim which prevents the rotation of said flanges. The pins 27 are carried by the casing parts. 28 is a helical spring which has one of its ends disposed over each of the flanges 26. It will be'seen thatiby rotating the adjusting` studs 22 that the flanges 26 will be moved toward or from each other, thus adjusting the compression on the spring 28 and thereby changing the i only necessary toshift the position of the speed vat which the governor will operate.

Referring now to Figs. 3 Yand 4, the casing parts 29 are pivotally mounted vupon the central shaft 30 in a similar manner to that shown in Fig. 1. The ears 31v provided at the upper end of the shaft30 are each provided with a plurality of Iapertures'32. 34 are the levers of the governor which are also Yprovided. with a plurality of apertures 35 so arranged that any of the apertures 35 in the levers may engage with any of the registering apertures 32 in the ears 31. By chang-l ing the lever pivot pins 47 so that they en-Y gage different pairs of registering apertures the multiplying effect of the governor will thereby bei altered. VI The outer ends-36 of each of the levers 34 are disposed within bushings 37 carried by the casing parts 29. rIhe inner ends 38 oftheV levers'34 are disposed within a central longitudinal slot 39 formed in the central spindle 40 of the governor. The ends 38 ofthe levers 34 are made substantially one-half the thickness of the other part of the lever and are so arranged that they lie in contact with each other withinthe slot 39 asy clearly shown in-Fig.` 4. In this form 4of my device, the joint between the casing parts'is cut away at the Yjoint lbelow the pivotpin, as shown by the broken lines in Fig. 3.V These casing part-s are pro-y vided at their lower portions with adjust-A ing studs 41 which are '-screwthreaded to the casing parts and provided at their inner ends with a head and flange 42 and 43, respectively, for the reception ofthe ends of the helical spring 44. This spring 44 isV disposed in an aperture 45 formed in the central shaft 30 and by adjusting the saine the speed at which the device will govern may be altered. The spindles l2 and 40 are each connected to the valve or devicevwhich controls the flow of motive fluid to the engine or apparatus being governed, in any of the ways well known in the art. l

When my governor is in operation, the weighted portions of the casings will be thrown outwardly by centrifugal force and against the compression of the helical' springsrQS or 44. As these weighted 'portionsare thrown outwardly the casing parts arecaused to be rotated lslightly about their pivot points, thus moving the bushings 20 (Fig. 1) upwardly and the bushings 37 (Fig. 3) downwardly. As these bushings are moved they likewise Vmove the outer ends of the levers 14 and 34 connected therewith.

In the form of my device shown in Fig. 1, when the outer ends of the levers 14 are moved upwardly the spindle 12 will be moved downwardly through the medium of inner ends of said leversand thus control the throttling mechanism to which the governor is connected. When it is desired to change the. multiplying effect of the governor it lis pins 19 carried at the upper ends fof the links 17 to another one'of the holes 16 prorvided in the levers 14.

TWhen the levers 34 in the form of the device shown in Fig. 3 are operated downwardly they raise the spindle 40 upwardly and thus control the movement of the throt-r tle. To change the multiplying effect in this Obviously, modifications may bemade of 'A the details herein shown and described, without departing lfrom the spirit of my inven-V t-ionor the scope of the appended claims, and I do not wish to be limitedto the exact embodiment herein shown and described.
